Transcranial Doppler ultrasound in the acute phase of aneurysmal subarachnoid hemorrhage.
Angiographic studies suggest that acute vasospasm within 48 h of aneurysmal subarachnoid hemorrhage (SAH) predicts symptomatic vasospasm. However, the value of transcranial Doppler within 48 h of SAH is unknown. ⋯ Early elevations of mBFV correlate with acute angiographic vasospasm and are associated with a significantly increased risk of DCI. Transcranial Doppler ultrasound may be an early useful tool to identify patients at higher risk to develop DCI after SAH.

Classification of minor stroke: intra- and inter-observer reliability.
The Oxfordshire Community Stroke Project (OCSP) and Trial of ORG 10172 in Acute Stroke Treatment (TOAST) classifications are widely used for the assessment of major ischaemic stroke. We explored their intra- and inter-observer reliability in the classification of outpatient minor stroke. ⋯ Our results may reflect the limited validity of these classifications in a typical minor stroke outpatient population and variable observer expertise.

Recovery after ischemic stroke: criteria for good outcome by level of disability at day 7.
Ischemic stroke is a leading cause of morbidity. Assessing the chances of recovery is critical to optimize poststroke care. ⋯ We identified clinical variables that predict good outcome, are specific to each day 7 mRS tier, and enable easy and informative assessment of the patient's likelihood of achieving varying degrees of recovery at day 90. These results may be useful in both clinical practice and research but require validation in an independent patient cohort.

Hyperdense middle cerebral artery sign on admission CT scan--prognostic significance for ischaemic stroke patients treated with intravenous thrombolysis in the safe implementation of thrombolysis in Stroke International Stroke Thrombolysis Register.
Hyperdense middle cerebral artery sign (HMCAS) on CT scan before stroke thrombolysis is associated with increased risk for haemorrhage and unfavourable outcome in several small studies. ⋯ HMCAS patients had severer stroke and a worse 3-month outcome. The risk for SICH per the SITS-MOST definition was similar compared to non-HMCAS patients, although increased per the RCT definition. There is not sufficient evidence to exclude these patients from intravenous thrombolysis. Combined treatment approaches might be considered in the perspective of the severe outcome and evaluated in RCTs.

Early administration of low molecular weight heparin after spontaneous intracerebral hemorrhage. A safety analysis.
Venous thromboembolism (VTE) is a common complication after stroke. Application of low molecular weight heparins (LMWH) has been proven to be beneficial for the prevention of VTE in ischemic stroke patients. However, there is no consensus whether and how to administer LMWH for prevention of thrombotic complications after acute spontaneous intracerebral hemorrhage (sICH), the main concern being possible hematoma growth. The objective of this study was to assess the safety of early subcutaneous LMWH in patients with sICH with respect to hemorrhage enlargement. ⋯ Early application of subcutaneous LMWH for prevention of venous thromboembolism seems to be safe, and probably does not increase the risk of hematoma growth in patients with sICH.
